I seen one person with an engine with no paint just sand blasted and it looked cool but I can't find it. Any body have pics of an engine with a gray color. I tried painting my engine it came out good but when I tried to put clear on in it got messed up..If I get in sand blasted again I'm thinking of just clearing it. Less paint maybe it will stay at a cooler temp .....http://i1237.photobucket.com/albums/ff473/mac2mac2/02112011356.jpg ....http://i1237.photobucket.com/albums/ff473/mac2mac2/03062011392.jpg
